JAMES H. NORTHROP, OF HOPEDALE, MASSACHUSETTS, ASSIGNOR TO GEORGE DRAPER& SONS, OF SAME PLACE.

SPINDLE FOR LOOM-SHUTTLES.

SPECIFICATION forming part of Letters Patent No. 454,811, dated June 23,1891.

Application filed March 23,1891. Serial No. 386,045. (No model.) I

To all whom it may concern.-

Be it known that I, JAMES H. NORTHROP, a subject of the Queen of GreatBritain, but residing at Hopedale, county of \Vorcester, State ofMassachusetts,have invented an Improvement in Spindles forLoom-Shuttles, of which the following description, in connection withthe accompanying drawings, is a specification, like letters on thedrawings representing like parts.

I have described in application Serial No. 380,494 a loom containing ahopper provided with spindles containing filling, the said loomcontaining a pusher to push the spindles from the hopperinto a shuttlein the shuttlebox of the lay, the said shuttle being open at one sidefor the reception of a full spindle and at another side for thedischarge of a spent spindle.

The spindle herein shown is designed to be used in connection with aloom-shuttle of the class referred to, although it might be used withany suitable shuttle having proper holding devices to retain the head ofthe spindle.

In accordance with this invention a metallic spindle is provided with ahead having an annular rib or projection adapted to be engaged by jawsof a shuttle, the said jaws having a corresponding rib or projection.Preferably the spindle will be of the split or expansible variety. Thespindle may have yarn spun on it, or a cop-tube filled with yarn may beplaced, and this spindle may be thereafter put into the shuttle.

Figure 1 shows a spindle embodying my invention; Figs. 2 and 3,modifications; and Fig. 4 shows a part of a shuttle with jaws adapted tohold the head of the spindle.

My improved spindle has a metal blade a, and preferably this blade willbe made expansible or be a split blade. The construction of the blademay correspond with any usual form of spindle-blade adapted to carry andkeep in place a cop-tube or bobbin containing filling. The enlarged headd of the spindle is substantially circular in cross-section, and toenable the -jaws b of the shuttle S to hold the spindle in horizontalposition and against endwise motions said head is provided with one ormore annular ribs or projections e to be engaged bycorrespondinglyshaped ribs or projections of the jaws b. The head shownin Fig. 1 is supposed to be composed of a circular block of metal and acylindrical jacket f of wood having ribs or projections of wire laidabout it.

In the modification Fig. 2 the entire head 77. maybe of metal or ofwood, and the rib or projection may be formed integral with the head,the projection standing out and being convexed.

In the modification Fig. 3 the spaces between the projections areconcaved. This invention is not, however, limited to any exact shape ofthe projections in cross-section.

The use of the wooden jacket fiends to cheapness of construction, forthe wire projections could not be as well retained in place on a plaincylinder of iron, and to solder the wire in place or have annulargrooves would add to the cost of the spindle.

The spindles are handled very carelessly by the operatives, and the ribsor projections have to be strong and of such construction that theycannot be bent out of shape by throwing the bobbins into boxes.

I am aware that a shuttle-spindle has had an annular groove to beentered-by a springpressed pin carried by a head pivoted in a shuttle,as in'United States Patent No. 21,068; and I am also aware that aspindle has had two notches opposite each other to co-operate with ahead pivoted in a spindle and with a pin fixed in a shuttle, as inUnited States Patent No. 2,489.

I claim- 1. A loom-shuttle spindle provided with a head having oneormoreribs or projections adapted to be embraced and held by jaws of ashuttle, substantially as described.

2. An expansible spindle having a head provided with one or more ribs orprojections adapted to be held by the jaws of a shuttle, substantiallyas described.

3. A loom-shuttle spindle having a head provided with a non-metallicjacket, to which are applied one or more annular ribs or projections,substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JAMES H. NORTHROP.
